SA24836

VERIFY ADVISORY:
http://secunia.com/advisories/24836/

CRITICAL:
Moderately critical

IMPACT:
Manipulation of data, Exposure of sensitive information

WHERE:
>From remote

SOFTWARE:
AlstraSoft Video Share Enterprise 4.x
http://secunia.com/product/13879/

DESCRIPTION:
VietMafia has reported some vulnerabilities in AlstraSoft Video Share
Enterprise, which can be exploited by malicious users to conduct SQL
injection attacks, and by malicious people to disclose or modify
sensitive information.

1) Missing authentication checks when accessing
siteadmin/useredit.php can be exploited to disclose or modify user
information.

2) Input passed to the "id" parameter in msg.php is not properly
sanitised before being used in an SQL query. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation of 2) requires user registration.

SOLUTION:
Restrict access to the "siteadmin/useredit.php" script (e.g. with
".htaccess").

Edit the source code to ensure that input is properly sanitised.

PROVIDED AND/OR DISCOVERED BY:
